When facing torvald use your turrets as decoy and get out of range of his beam, try to bring him to your damage dealer and keep spawning turrets to heals and disrupt his attack

It can be useful to bait him with your shield, and then use Rocket boots towards cover. Still an extremely difficult match-up, unless you have a DPS that is on-point with taking him out.

The shield can be used to interrupt his lock on attack. Best used in the beginning of a fight as he can't siphon higher shields then he already has at full health.

You can absorb Bariks Barricade with ease, so his shield will be worthless
